Humans can design almost anything - being practical that's another thing altogether.
I need some parameters:
1. number of birds - I have a small 4X8 ft shelter that will fit on our trailer. It has a bolted in perch and can have a nest box popped in, and when I had a 5 chicken remnant flock they were happy to call it home while fertilizing and cleaning up under my fruit trees and being moved once per day. I considered 5 birds pushing the occupancy - 4 would be better. They didn't have enough space to get most of their calories from the land, but my fruit trees appreciated them, and their quality of life was acceptable. It was light weight, and had wheels I could add or remove, so one person could move it easily.
2. predator pressure - a movable shelter that moves regularly will confuse some predators. Removing feed at night and teaching the birds to clean up their feed will help - rats like chicken feed, predators like rats, if the predators follow the rats to your chickens, the chickens will loose.
3. Aerial predators - Having a secure night/nest/food portable shelter and then letting the birds free range or have electric fencing during the day may work if the aerial predator pressure isn't too great. Again - moving the birds frequently (like weekly) will help with predator pressure. Even having some worn-out table umbrellas that move each day in the open space can keep the hawks/crows away (we hammer a piece of rebar into the ground and slide the metal pole of an umbrella over it to stay upright for meat chickens.) If the pressure from above is high enough you need netting over the area, that's much harder to manage on a portable system and still have it quick and easy to move.
Basically, in a perfect world, I would prefer to have multiple paddocks which would allow me to plant lots of chicken-friendly shrubs/bushes and with *lots* of mulch to encourage bugs (chickens are *much* more bug-avores than most people appreciate) and a light-weight portable night lock-up that would move weekly - it's in my plans. Most of the portable shelters I've met that are either large or complicated end up being left in one spot, because it is *really* hard to design them light enough. Our 10x12 ft shelters for hubby's professional egg laying business are marginal for me to move independently and they can only be moved on fairly flat ground over grass/low forbs. The only portable fencing I use regularly is dog exercise pen fencing and even the khakis can get over it - layers would in a heartbeat! I suspect the layers that stay in electric net fencing (ENF) have had one wing trimmed, but that makes it harder for them to perch high at night -higher perches helps keep the rats pressure down. Also, I and others have found that ENF is hard for a single individual to set up - two people is better, the places I've seen it used regularly had 3 people. That is assuming you don't grow rocks as well as we do!
So the short answer is yes, you can, although many of the larger ones I've seen are actually built onto a trailer base permanently. There are simply so many variables, that the longer answer is maybe. Decide what would be the most important parameters, google images and post links along the lines of what might meet your needs, and lots of people will help you problem solve from there.
